Background and Purpose
Internationally, postoperative pancreatic fistula (POPF) remains a leading cause of morbidity and mortality after pancreaticoduodenectomy (PD). In order to reduce the incidence of POPF, a number of technical modifications for pancreato-enteric anastomosis after PD have been proposed. In 1995, we established a new technique with transpancreatic transverse U-sutures for end-to-end invaginated pancreaticojejunostomy after a PD, and the preliminary results were quite encouraging. This study aims to review a new surgical approach, the Chen’s U-stitch technique, for end-to-end invaginated pancreaticojejunostomy, which involves two to four transpancreatic transverse U-sutures, and to evaluate the effectiveness of this approach with reducing the incidence of POPF formation.
To evaluate this new approach, during 2002–2012, a total of 264 patients who received the new Chen’s U-stitch technique after a PD were included in this study. Postoperative morbidity and mortality, including the incidence of POPF, were analyzed.
Postoperative morbidity was 22.3 % (59/264) and mortality was 0 % (0/264). The POPF rate was 3.4 % (9/264) for Grade A, 0.8 % (2/264) for Grade B, and 0 % (0/264) for Grade C.
This new surgical technique (Chen’s U-stitch), which involves an end-to-end invaginated pancreaticojejunostomy with two to four transpancreatic transverse U-sutures, provides excellent outcomes at reducing the incidence of POPF after PD.
